Definitions

  • TECHNICAL FIELD This invention relates to sodium barium borosilicate glass compositions. Fibers from these compositions make glass fiber insulation.
  • the insulation is well known and has been a commercial product for a long period of time.
  • the insulation is made from intertwined soda lime alumina borosilicate glass fiber which a binder holds together.
  • the binder may be any suitable material but quite commonly is a phenol-formaldehyde resin or a ureaformaldehyde resin.
  • binders are well known, and a spray nozzle generally applies them to the glass fibers as hot gases attenuate the fibers from a rotating device, commonly called a spinner.
  • a conveyer collects the binder-coated fibers in the form of a blanket, and heat cures the blanket to produce the final insulation. The process produces various densities by varying the conveyor speed and the thickness of the cured insulation.
  • German government has proposed regulations for glass fibers. Glass fiber compositions meeting the regulations are considered to be free of suspicion. The problem, however, for the manufacturer is to produce glass fibers which meet the regulations and standard criteria. These glasses must meet the proposed regulations, be fiberizable in standard wool processes, have sufficient durability, and have acceptable insulating properties.
  • each glass composition has a KI value equal to or greater than 40.
  • the glass compositions consist essentially of: Ingredients Weight Percent
  • each glass composition has a KI value equal to or greater than 40.
  • the glass compositions have a BaO content of 5 to 30 weight percent and less than about 2% of any or all of ZnO, TiO 2 , Fe ⁇ j , ZrO 2 , SrO, or LLp. Even more preferably the glass compositions have a BaO combat of 12 to 25 weight percent, and less than 2% of any or all of ZnO, TiO 2 , F ⁇ jOj, ZrO 2 , SrO, or Li j O. Insulation products of these glass fibers can be produced from a conventional fiber-forming process.
  • the German regulation requires a numerical index (KI) greater than or equal to 40 to be considered free of suspicion.
  • These glasses however, have poor durabilities and most could not be fiberized by a standard wool process.
  • Example 1 Examples of the compositions are given in the following table. All the glass compositions have KI index of 40 or higher. Example 1
  • Glass fibers of the present invention have the following compositions. Most of the compositions have measured forming temperatures (the temperature where the viscosity of the glass is about 1,000 poise) and liquidus temperatures.
